ADJUSTABLE FLUE CLEANER ts. HEAT nanrai onsi Application filed February 20, 1919, Serial No. 273,145, Renewed August 22, 192 2 S'erialNo. 583,632.

To all whom it may concern p Be it known that I, WILLIAME. .BAHR,

a citizen of the United States of America,- residing at Washington, in the District ofv Columbia, have invented certain new and useful Improvements in Adjustable Cleaners for Heat Radiators, of which the following is a specification.

The primary object of the invention is the provision of an auxiliary flue heater whereby the waste products of combustion from any burner may be utilized for heating purposes thereby utilizing heat units without additional expense and which would otherwise be lost, advantageous cleaning means being incorporated in the structure normally maintaining the same at a high degree of efiiciency.

A further objectof the invention is to provide an auxiliary flue heater with a simple' and eflicient means for successively cleaning the plurality of fiues thereof with out the necessity of employing an outside cleaner, the device being readily adjustable during the cleaning operation which is accomplished in a cleanly and sanitary manner by preventing the escape of any gases or dirt from the device while cleaning the same.

With these and other objects in view, it will be readily apparent as the nature of the invention is better understood, the same consists of the novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying,

drawing and then claimed; In the drawing forming a part of this application and in which like characters designate corresponding parts throughout the several views,

Figure 1 is an elevational view ofmy in vention in its entirety. v, v

Figure 2 is a longitudinal sectional view taken therethrough axially of one of the flues thereof and illustrating the cleaner in its normal enclosed position.

Figure 3 is a fragmentary view taken radially of one of the drums or heads of the device showing the pivotal connecting means.

Figure 1 is an end elevational view .of the invention and Fi re 5 is a View similar to Fig. 1 with the revoluble end cap with the cleanerv and accompanying parts removed.

My improved radiator and cleaner consists of oppositelypositioned I tubular heads or drums '10 and 11, either of. whichmay constitute theinlet or= outlet drum forproducts of combustion derived from any manner of burner or heater such as a coal, wood,

gas or oil burner, a plurality of tubes or flues 12 connecting the said drums together for the passing of products of combustion therethroiligh, while similar thimbles' 13 "and la-com municate with" the interior of the drums-1O and 11 respectively being relatively mounted thereon at any point and in any manner desired. My invention is designed for positioning in a room or compartment at any su table distance from the main burner or heaterwith one of said thimbles 13 and- 141 adaptedto receive the products of combustion therefrom "while the other'thimble serves asan outletcommunicating with the discharge flue or "chimney. The waste products of combustion which are passed in-this mannerthrough my device effect a heating of the. surrounding atmosphere by the free radiation of heat units without adding to the expense of operatingthe main heater. It will be understood that my invention may be positioned vertically, horizontally or otherwise as-found desirable, is ornamental in appearance and consumes but little room while performing itsfunction of heat radiation. j

'One of the drums such as 11 has a closure cap 15 in the form ofa disk; revolubly mountedrthereon with an annular flange 16 fitting within the end of the drum while the peripheral portion 17 of the disk 15 projects outwardlyof-the flange 16 beyond Y the upper edge or rim 18 of the drum ll'. A bolt. 19 is centrally journaled through the drum 11 and through the disk 15 having a head 20 beneath the drum-between the fines 16 while a washer 21 and'a removable'nut22 are provided upon the opposite end of the bolt 19 outwardly of the cap 15 whereby the latter is ,rotarily mounted upon I I the drum 11. A suitable form of cupdetail sectional shaped plug or closure 23 is normallymaintained by friction in its closing position in .a circular opening 24 through the cap 15,

the said opening being eccentrically positioned adapted for axial alignment withall of the fines 12 during each revolution of the cap 15. A cleaner for the fines 12 con- 1 sists of a rod 25 slidably mounted through the plug 23 and extending through the drum 11 for normal positioning axially of any one of the flues 12 as best illustrated in Figure 2 of the drawing, a cleaning head or enlargement 26 upon the end of the rod 25 being normally positioned in the opposite drum whenthe cleaner is not in use.

A cylindrical handle 27 upon the opposite end of the rod outwardly of the plug 23 is adapted toimpartlongitudinal sliding movement to the rod25 for forcing the head 26 through the adjacent flue l2for. cleaning the same of soot and dirt accumulations therein, the handle 27 having a suitable packing 28 preventing the escape of any products of combustion fromthe drum 11 :around the rod 25 when the cleaner is not in use.

Aspring 29 is riveted or-otherwise sccured as at 30 exterio'rily of the drum 11 having a free end portion 81 triangular in cross section adapted for engaging within spaced notches 32 in the peripheral-portion of the cap 15 when the opening 25 is positioned in axial alignment with the separate flues12 for accuratelypositioning the rod 25 for the cleaning thereof.

The complete'operation of the invention will be fully :understood from this detailed description thereof, the device being installed as noted and preferably positioned vertically as herein illustrated, the rod 25 may be Withdrawn by means-of its handle 27 positioning the cleaning head 26 Within the drum 11 and permitting the free rotation of the cap 15 for engaging theaspring portion 31 successively in the notches'32 where by the reciprocations-of the rod 25 successively cleans the fiues 12 as heretofore noted.

A compact formof auxiliary radiator is provided that is readily kept free and clean from soot and dirt in the manner described for-rendering thesame fully etlicient at all times, for the passing of waste products of combustion therethrough and utilizing such erably rounded permitting the ratcheting rotation of the cap 15 for-removing and reproducts for suitable heating purposes. The spring end 31 has its apex. 33 prefseating the spring successively in the notches 2-32 it being understood that the said notches are radially. arranged relativelyof the pivot bolt 19 for passmgthrouglr the axialplanes of the fines 12, the opening-24- beingin the radial line of one of said notches 32 in a radial -distancecorresponding; to the axes of the flues 12 relatively of said bolt 19.

. lVhilethe form of the invention herein shown and described is. What is believed to be the preferred embodiment thereof, it is nevertheless to be understood that various forms, modifications and arrangements of the parts may be made without departing from the spirit and scope of the invention as claimed. i

What I claim asnew is 1. A device of the class described including inlet and outlet drums for products of combustion connected by a plurality of radiating fiues, a closure cap journaled upon the end of one-of said drums having aprojecting peripheral portion provided with notches outwardly. of the rim of the drum spaced apart upon radial lines passing through the plancs'of the axes of said fines,

a. spring retainer exteriorly carried by said drum having a triangular end adapted for seating successively within said notches and a removable cleaner slidably positioned through the. cap and adapted for operative *rcgistering with said fiues during the seating of the spring within the notches.

. 2. A heat radiator comprising a drum, flues concentrically projecting from one end thereof, a disk upon the opposite end of the drum centrally journaled for rotation thereon, and having an opening adapted for successive registry with said flues, during the turning of thedisk, the said disk having a through the plug axially ofthe opening,

adapted for reciprocation throughsaid flues, successively, a headupon the inner end of said rod, a handle upon the opposite end of the rodoutwardly ofthe plug, and a pack ing upon the rod at the inner end of the handle adapted for seating upon the plug to prevent the escape of gases and particles from thcdrum when the drum is in use as a heater.
